Justification:
The extent of occurrence (EOO) of this speciescovers less than 700 km2. This geographic range is severely fragmented and undergoing continuing decline in area, extent and quality of habitat. Based on these premises, the species is listed as Endangered.

This species is presently known only from Manongarivo Special Reserve in northwestern Madagascar, from an isolated population on the Ampasindava Peninsula, and possibly from the forests of Mahilaka-Maromandia (Mittermeier et al. 2008). It lives from 360 to 1,600 m above sea level. The extent of occurrence (EOO) is estimated as less than 700 km2.

The Sambirano Mouse Lemur is named for the region where elements of Madagascar’s humid eastern and dry western forests meet. It can be found in disturbed habitats and in forests bordering agricultural sites. It has been observed in a garden close to secondary forest. No systematic studies of this species’ ecology or behaviour have been conducted to date.

This species is listed on Appendix I of CITES. The only protected area where it is known to occur is the Manongarivo Special Reserve. There are no specimens reported in captivity at this time (ISIS 2009). The remaining forest on the Ampasindava Peninsula requires protection.
